  • Patent number: 11588216
    Abstract: One or more external connectors of a conformal wearable battery (CWB) may be controlled to reduce a voltage potential supplied to the connectors when exposed to a conductive liquid. The connectors may be uniform serial bus (USB) connectors or other connectors. One or more unused terminals of the one or more connectors may be pulled to a voltage potential and then monitored for a change in voltage. When the change in voltage satisfies a voltage threshold, the voltage potential supplied to the one or more connectors may be reduced and/or interrupted. The change in voltage may be evaluated against the voltage threshold alone or may be evaluated against the voltage threshold and a time threshold relating to a time after the voltage satisfied the voltage threshold. Based on the voltage threshold having been met, the voltage supplied to the connector may be reduced or stopped.
